Longer delay can also be used for TIG welding
in order to prevent the filter opening when the
light path to the sensors is temporarily
obstructed by a hand,torch,etc.
5-4. Selecting Sensitivity
The sensitivity can be set at "HI" (High)or "LO"(low)by using the infinitely dial knob.(See Fig.7)
As a simple rule for optimum performance,it is recommended to set sensitivity at the High at the welding light flashes
and without annoying spurious triggering due to ambient light conditions(direct sun, intensive artificial light,neigh-
boring welder' sarcs etc.).
"HI" (High)-Most for welding applications but specially for low welding current work,
"LO" (Low)-Only in some specific surrounding lighting conditions in order to avoid unwanted triggering.
5-5. Power
All the welding helmets are powered by solar energy. Some of models are without replaceable batteries. Some select-
ed models need to replace Li-Batteries when LOW BATTERY Light starts blinking.
Instructions for replacement of batteries
REPLACING THE ADF BATTERY
It is essential that when replacing the battery that it is mounted the correct way up as the illustration
